Description

Technical Field

[0001] The present invention relates to the technical field of gate opening and closing equipment, and in particular to a gate opening and closing machine. Background Art

[0002] Gates are critical devices used to block or clear water flows and are widely used in reservoirs, canals, sewage treatment plants, pumping stations, and other locations. Hoists are the actuators that control the opening and closing of gates. In actual operation, especially in areas with high sediment loads or stagnant water, sediment deposition and siltation are highly likely to occur at the base of gates and in the surrounding areas. Over time, the solidified silt can create significant forces and static friction on the gates.

[0003] At present, the conventional technical solutions to the gate siltation problem are mainly divided into two categories. One is passive dredging, which uses external equipment such as dredgers, dredging robots or high-pressure water guns to perform dredging operations first; the other is enhanced opening and closing, which simply increases the power and torque of the opening and closing machine, trying to rely on greater opening and closing force to forcibly overcome the silt resistance and open the gate.

[0004] Although these two dredging methods can be used, they have obvious disadvantages. The former has the problems of long operation cycle, high cost and low efficiency. The latter can easily cause serious damage to the sealing surface of the gate, resulting in water leakage after the gate is closed and loss of the interception function. In more serious cases, it may cause structural damage such as gate deformation, damage to the gear or screw of the gate hoist, resulting in huge maintenance costs and downtime losses.

DETAILED DESCRIPTION

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0022] In one embodiment, see Figures 1 to 2 As shown, the present invention provides a gate hoist, comprising: a frame body 1, a hoist body 2, a valve body 3 and a stirring assembly.

[0023] The frame body 1 has a vertically arranged sliding channel 101. The frame body 1 is usually welded from steel sections and fixedly installed at a water conservancy channel or a pipe opening to guide the lifting of the valve body 3.

[0024] The hoist body 2 is fixedly connected to the frame body 1 by bolts or welding, and has a lifting end 21 that can move vertically. Among them, the lifting end 21 adopts a screw structure, and the hoist body 2 can drive the lifting end 21 vertical displacement by electric or manual means.

[0025] The valve body 3 is slidably mounted in the sliding channel 101 and fixedly connected to the lifting end 21 by a pin connection. A guide wheel is fixed to the side wall of the valve body 3 by bolts, and the guide wheel is slidably mounted in the sliding channel 101.

[0026] The stirring assembly is fixedly connected to the valve body 3 and includes several groups of stirring units 4. A rotatable stirring head 41 is provided at one end of the stirring unit 4 facing away from the valve body 3. The rotation direction of the stirring head 41 is set along the width direction of the valve body 3. A nozzle rod 42 is provided at one end of the stirring head 41 facing away from the valve body 3. The nozzle rod 42 is set along the center line direction of the stirring head 41. A jet flow channel 401 is provided in the stirring unit 4. The end of the jet flow channel 401 has a nozzle opening 402. The nozzle opening 402 is opened on the outer wall of the nozzle rod 42. A plurality of stirring blocks 43 are provided at one end of the stirring head 41 facing away from the valve body 3. The stirring blocks 43 are arranged in a ring shape with the nozzle rod 42 as the center line. There is a stirring gap between the stirring blocks 43, and the injection angle of the nozzle opening 402 can pass through the stirring gap. Among them, the cross-section of the stirring block 43 can be rectangular, trapezoidal or blade-shaped, which is used to cut and stir the deposited silt during rotation; the jet channel 401 is connected to an external high-pressure water pump through a pipeline connection; the rotation direction of the stirring head 41 is along the width direction of the valve, which can effectively clean the area directly below the valve that is most prone to siltation; the design of the nozzle mouth 402 precisely aligning with the stirring gap ensures that the high-pressure water flow can maximize the effect on the stirred silt, with high energy utilization rate; the structure of the stirring component is compact, which is not only suitable for new construction projects, but also convenient for the transformation and upgrading of existing gates, and has broad application prospects.

[0027] When the gate needs to be opened, the stirring assembly is first started, and the external high-pressure water pump injects high-pressure water into the injection channel 401, and sprays it out at high speed from the nozzle port 402. The driving motor drives the stirring head 41, the nozzle rod 42 and the stirring block 43 to rotate along the width direction of the valve. The high-speed rotating stirring block 43 is like a rotating blade, breaking up and crushing the silt layer at the bottom and around the valve. The high-pressure water flow ejected from the stirring gap performs a secondary impact and dilution on the crushed silt, forming a mud-water mixture. After a period of time, the hoist body 2 is started again to lift the valve body 3. In this process, the liquefied silt is more easily washed away by the water flow, thereby greatly reducing the resistance to valve startup and effectively preventing problems such as blocking, sealing surface strain and hoist overload caused by siltation.

[0028] In summary, this example can actively remove silt deposits at the bottom and around the valve before opening the gate through the combined synergistic effect of the mechanical stirring of the stirring component and hydraulic flushing, avoiding the technical difficulties of the gate being stuck and unable to open and close normally due to silt accumulation. At the same time, since the solid silt layer has been liquefied or removed before opening the gate, the static friction that needs to be overcome when the valve is started is greatly reduced, reducing the traditional forced opening and closing of the silted gate, which is very likely to damage the valve sealing surface and even cause the valve body to deform, avoiding equipment damage caused by overload, and extending the service life of the entire device. In addition, the stirring component is integrated with the valve body 3, and no additional independent dredging equipment is required. The operation process can be linked with the gate control system to achieve automatic operation, thereby improving work efficiency and intelligence.

[0029] In an alternative example, see Figures 1 to 6As shown, the stirring unit 4 includes a stirring shell 31 fixedly connected to the valve body 3, the stirring head 41 is connected to the stirring shell 31 by a rotational connection, the nozzle rod 42 extends into the stirring shell 31 at one end thereof facing the stirring shell 31, a waterway rotary joint 32 is fixed in the stirring unit 4, the waterway rotary joint 32 has a waterway rotating end 321, and the nozzle rod 42 is provided with a waterway flow channel 421 arranged along the axis of the nozzle rod 42 at one end thereof facing the stirring shell 31, one end of the waterway flow channel 421 is fixedly connected to the waterway rotating end 321, and one end of the waterway flow channel 421 is communicated with the nozzle opening 402, and the stirring shell 31 is rotated. A driven gear 33 is installed in a dynamic manner, and the rotation center line of the driven gear 33 coincides with the rotation center line of the stirring head 41. An elastic resistance piece 34 is fixed to the end of the driven gear 33 facing the stirring head 41, and a driving clamping ring 35 is provided at the end of the elastic resistance piece 34 facing the stirring head 41. A driven clamping ring 36 is fixed to the end of the stirring head 41 facing the driving ring. The water channel 421, the nozzle port 402 and the water channel rotary joint 32 are combined to form a jet flow channel 401. The stirring unit 4 includes a power mechanism for providing power, the power mechanism is fixedly connected to the stirring shell 31, and the power mechanism is meshed with the driven gear 33.

[0030] When the gate needs to be opened, the external high-pressure water pump is first started. The high-pressure water is delivered to the rotating nozzle rod 42 through the waterway rotary joint 32 and ejected from the nozzle port 402. At the same time, the power mechanism is started, and the torque is transmitted through the meshing of the driving gear and the driven gear 33. The torque is transmitted to the stirring head 41 through the elastic contact piece 34, the driving clamping ring 35 and the driven clamping ring 36, driving it to rotate together with the nozzle rod 42 and the stirring block 43. The rotating stirring block 43 cuts and breaks the compacted silt. The high-pressure water flow accurately ejected from the stirring gap immediately impacts and liquefies the broken silt. After a period of time, the hoist body 2 is started again to lift the valve to complete the gate opening operation.

[0031] Specifically, this example transmits torque through the elastic resistance piece 34, which not only ensures the stable cutting ability of the stirring block 43, but also has the ability to compensate for errors and buffer impacts, preventing large debris from getting stuck in the stirring head 41, thereby improving the reliability and service life of the transmission system, and delivering high-pressure water through the waterway rotary joint 32, achieving continuous and stable delivery of high-pressure water to the rotating spray rod, ensuring the continuous operation capability of the dredging function.

[0032] In an alternative example, see Figures 1 to 7As shown, the driving clamping ring 35 has a driving protrusion 351 at one end thereof that faces the driven clamping ring 36, and the driven clamping ring 36 has a driven groove 361 at one end thereof that faces the driving clamping ring 35 and matches the driving protrusion 351. A first wedge-shaped end surface is provided on the driving protrusion 351, and a second wedge-shaped end surface that matches the first wedge-shaped end surface is provided in the driven groove 361.

[0033] Specifically, when the torque of the driving clamping ring 35 is too large, the combination of the wedge-shaped end surface 1 and the wedge-shaped end surface 2 can generate an oblique force, causing the driving protrusion 351 to disengage from the driven groove 361, ensuring smooth operation under heavy loads and harsh working conditions.

[0034] In an alternative example, see Figures 1 to 9 As shown, the power mechanism includes a power motor 37 fixedly connected to the stirring housing 31 by a bolt connection. A power bevel gear 38 disposed in the stirring housing 31 is fixed to the output shaft of the power motor 37. A driven rotating shaft 39 is rotatably mounted in the stirring housing 31. A driven bevel gear 310 and a power gear 311 are fixed to the outer wall of the driven rotating shaft 39 by a key connection. The power gear 311 meshes with the driven gear 33, and the power bevel gear 38 meshes with the driven bevel gear 310. The power motor 37 is fixed to the outer wall of the stirring housing 31, and the output shaft of the power motor 37 extends into the stirring housing 31. When the power motor 37 is working, the output shaft of the power motor 37 drives the power bevel gear 38 to rotate, the power bevel gear 38 drives the driven bevel gear 310 to rotate, the driven bevel gear 310 drives the driven rotating shaft 39 to rotate, the driven rotating shaft 39 drives the power gear 311 to rotate, and the power gear 311 drives the driven gear 33 to rotate.

[0035] Specifically, the power mechanism of this example adopts a combined transmission scheme of bevel gears and cylindrical gears, so that the power motor 37 does not need to be installed coaxially with the stirring head 41. Instead, it can flexibly select the optimal and most space-saving installation orientation according to the spatial layout within the stirring shell 31, greatly enhancing the design flexibility and the compactness of the entire machine, and is very suitable for harsh environments where underwater installation space is limited.

[0036] In an alternative example, see Figures 1 to 9 As shown, a mounting groove 3101 is provided in the stirring shell 31, and a through groove 3102 is provided in the mounting groove 3101, which penetrates the stirring shell 31. A limit ring 312 is fixed to the end of the stirring head 41 facing the stirring shell 31 by means of a bolt connection. A rotating bearing 313 is inserted and fixed in the mounting groove 3101, and the limit ring 312 is fixedly connected to the inner ring of the rotating bearing 313. The limit ring 312 has a limit flange extending in a direction away from the center line of the limit ring 312, and the limit flange is inserted into the inner ring of the rotating bearing 313.

[0037] Specifically, this example reduces the manufacturing difficulty and cost of the stirring unit 4 by reducing the structure of the stirring shell 31 and the stirring head 41, thereby facilitating the maintenance of the stirring unit 4.

[0038] In an alternative example, see Figures 1 to 10 As shown, a first bearing seat 314 and a second bearing seat 315 are fixed in the stirring shell 31 by means of bolt connection, an extension convex ring 331 is provided on the driven gear 33, and the extension convex ring 331 is fixedly connected to the first bearing seat 314 by means of a bearing connection, and the driven rotating shaft 39 is fixedly connected to the second bearing seat 315 by means of a bearing connection.

[0039] Specifically, this example fixes the driven gear 33 and the driven rotating shaft 39 by the combination of the first bearing seat 314 and the second bearing seat 315, which effectively reduces the difficulty of installing the driven gear 33 and the driven rotating shaft 39 and facilitates the disassembly and assembly of the stirring unit 4.

[0040] In an alternative example, see Figures 1 to 10 As shown, a connecting bracket 316 is fixed in the stirring shell 31 , and both ends of the connecting bracket 316 are fixedly connected to the stirring shell 31 by bolt connection. The connecting bracket 316 is also fixedly connected to the waterway rotary joint 32 by bolt connection.

[0041] Specifically, in this example, the water channel rotary joint 32 is fixed by a leveling bracket, which effectively reduces the difficulty of installing the water channel rotary joint 32 and facilitates the disassembly and assembly of the stirring unit 4.

[0042] In an alternative example, see Figures 1 to 11 As shown, the elastic contact piece 34 includes a positioning ring body 341, which is provided with a plurality of extensions 342. A plug ring 317 is fixed to the end of the driving clamping ring 35 facing the positioning ring body 341. The outer wall of the plug ring 317 is provided with a clamping slot 3171 that matches the extension 342. The extension 342 is provided with a bolt hole, and the plug ring 317 can be fixedly connected to the driving clamping ring 35 by bolt connection. The positioning ring body 341 is also fixedly connected to the driven gear 33 by bolt connection.

[0043] Specifically, this example reduces the difficulty of installing the elastic resistance piece 34 by optimizing the structure of the elastic resistance piece 34 , and facilitates the disassembly, assembly and maintenance of the elastic resistance piece 34 .

[0044] In an alternative example, see Figures 1 to 11As shown, a cutting shaft 5 is mounted on the valve body 3 via a bearing connection, and a cutting telescopic cylinder 6 is mounted on the valve body 3 via a rotating shaft connection. The centerline of the cutting shaft 5 is arranged along the length of the valve body 3. A driving arm 7 and a plurality of cutting members 8 are fixed to the outer wall of the cutting shaft 5 via a bolt connection. The telescopic end of the cutting telescopic cylinder 6 is fixedly connected to the end of the driving arm 7 via a rotating shaft connection. When the cutting telescopic cylinder 6 is in operation, the telescopic end of the cutting telescopic cylinder 6 drives the driving arm 7 to rotate, which in turn drives the cutting shaft 5 to rotate, which in turn drives the cutting members 8 to rotate, causing the cutting members 8 to rotate away from the valve body 3. This can shear, tear, and clear away flexible obstacles such as ropes, aquatic plants, and fishing nets that are wrapped around the valve body 3, thus clearing the way for the normal opening and closing of the valve.

[0045] Specifically, this example uses the design of the cutting component to make it suitable for waters with lush aquatic plants, frequent fishing activities, or a lot of garbage. It can effectively deal with the entanglement and blocking problems that traditional gates cannot cope with, expand the application scenarios of the present invention, and directly integrate the cutting function into the valve body 3, eliminating the need for additional ships or divers for external cleaning, thereby realizing the automation and intelligence of underwater obstacle cleaning.

[0046] In an alternative example, see Figures 1 to 12 As shown, the cutting member 8 includes a plurality of support plates 81 spaced apart from each other, which are parallel to each other and spaced apart at a certain distance, forming a channel for capturing and cutting obstacles.

[0047] A main support 82 and several auxiliary supports 83 are fixed between the support plates 81 by welding. The main support 82 and the auxiliary supports 83 connect the support plates 81 into a solid overall frame, which greatly enhances the structural strength and rigidity of the entire cutting piece 8 and prevents it from deforming during cutting.

[0048] The main support 82 is provided with an axis through groove 821 matching the cutting axis 5, and the end of the support piece 81 is provided with an arc portion 811 facing away from the valve body 3. The arc portion 811 can be a smooth curved surface or a hook-shaped structure with a cutting edge.

[0049] Specifically, this example forms a high-strength, high-rigidity cutting piece 8 through the cooperation of the support plate 81, the main support 82 and the auxiliary support 83, so that the cutting piece 8 can withstand huge cutting forces without structural deformation or damage, thereby ensuring the service life of the cutting piece 8.

[0050] In general, this valve can actively clear the silt deposits at the bottom and around the valve before opening the gate through the combined synergistic effect of the mechanical stirring of the stirring component and the hydraulic flushing, avoiding the technical problems of the gate being stuck and unable to open and close normally due to silt accumulation, realizing automatic operation, and improving the working efficiency and intelligence level of the gate opening and closing machine. In addition, the torque is transmitted through the elastic resistance piece 34, which not only ensures the stable cutting ability of the stirring block 43, but also has the ability to compensate for errors and buffer impacts, avoiding large debris from getting stuck in the stirring head 41, improving the reliability and service life of the transmission system, and at the same time adding a cutting component, so that it can be used in waters with lush aquatic plants, frequent fishing activities or a lot of garbage, and can effectively deal with the entanglement jamming problem that traditional gates cannot cope with, expanding the application scenarios of the present invention, and realizing the automation and intelligence of underwater obstacle cleaning.
